Abstract

A method of making a turbine blade from nickel-chromium alloy comprise the following steps in the order stated or with step (2) preceding step (1): (1) partially forming a blade blank from stock material; (2) giving solution heat treatment at 1050-1200 DEG C. for 10 to 2 hours; (3) polishing the blade by electro-polishing or mechanical methods; (4) covering the blank with a protective coating; (5) heating the blank to a forging temperature of 1100-1225 DEG C. for 1 to 20 minutes; (6) forging at least the blade profile to finished size between dies; (7) heat treating for precipitation hardening at 700-800 DEG C. for 20 to 10 hours. The nickel-chrome alloy comprises at least 50 per cent nikel or nickel plus cobalt (cobaltt not exceeding 45 per cent of the alloy), 5 to 45 per cent chromium, and one or more of the elements molybdenum, tungsten, iron, manganese, aluminium, vanadium, titanium, niobium, silicon, carbon. Before the precipitation heat treatment (7) the blade is preferably heated to 1080-1150 DEG C. for 30 to 5 minutes to remove internal stresses as described in Specification 674,724. After the heat treatment the protective cotaing is removed by electro-polishing as described in Specification 670,542, [Group XXXVI]. Alternatively it may be removed by vapour or shot blasting and the blade is subsequently electro-polished. Specifications 585,845 and 659,573, [Group XXII], also are referred to.
